Gas: On-site calibration optimised at the metering skid

On-site calibration of measuring instruments is often very time-consuming and expensive. This is especially true for applications with several measurands. One example of this is the metering skid, a system for the custody transfer measurement of the amount of natural gas transferred. A global player in the market from Saudi Arabia has now significantly streamlined the testing process at this point: with the multi-functional CPH8000-P1 calibrator from WIKA, a ?calibration laboratory in an incident?.
The heart of a metering skid may be the flow computer. Remarkable processes the info from all of the measuring instruments and calculates the exact amount of natural gas that flows to the customer. Natural gas is compressible, so the tabs on pressure and temperature during gas transfer plays an essential role.
Verification may be the law
Because even small measuring errors can cause noticeable losses in turnover, the measuring instruments must be calibrated regularly. Normally, this is done at the facility. Each on-site calibration must be verified relative to regulations. This implies proving consistent repeatability of the test outcomes and traceability to the assigned references. In addition, the regulations require the test equipment to be approved for used in hazardous areas.
In view of certain requirements, the calibration personnel of WIKA customers previously had to use many different pieces of equipment so that you can adequately fulfil their tasks. As well as pressure and temperature calibrators, this included a pneumatic pump for the test pressure, a HART� communicator and a resistance decoder. The on-site calibration cost effort and time accordingly.
The CPH8000-P1 multi-functional calibrator significantly reduces your time and effort necessary for on-site calibration.
Four measuring channels
The natural gas company in Saudi Arabia has reduced this effort in a single fell swoop with the CPH8000-P1 portable multi-function calibrator from WIKA. The case-mounted instrument calibrates pressure measuring instruments as well as resistance thermometers and thermocouples. The test pressure is generated having an integrated pump. The CPH8000-P1 has four measuring channels. Pessimistic could thus perform and display around four measurements simultaneously. Formula -approved version also supplies the test items and reference sensors in the metering skid with voltage (DC 24 V) without danger.
Documentation without problems
During the test procedure, the CPH8000-P1 ? via its integrated HART� module ? communicates directly with the measuring instruments, which may also be HART�-capable. Its powerful data logger and the very large memory capacity support the user in the subsequent documentation of the on-site calibration. The unit provides all the information relevant for verification.
Note
Detailed home elevators the model CPH8000 multi-function calibrators can be acquired on the WIKA website. Each instrument includes a modular design and can therefore be specified for the respective range of applications. Should you have any more questions, your contact will gladly assist you to.
